non temperature management related stuff that helped me endure the 12 day heatwave:
and quite a big one: a not very efficient, but a very meditative way of journaling. one letter per square, then color in the spaces between words. that way i still express something, but it really doesn't have to be a lot to fill up the whole page. carefully color things in, arrive at a pattern. it's also cool to see the patterns on either side of a page interact through their ghosting. just a way to slow down and not escape from the discomfort. and with so much ink to use up i don't feel very wasteful, seeing so much color on a page.
